assignors to Aveo Corporation, Cincinnati, Ghia, a corporation of Belavvare Filed lidar. 22, 19..-3, Ser. No. 267,286 4 Claims. (Cl. Seil-9.45)

This invention relates to improvements in a moving events display device, that is, a device for automatically tracking time and/or distance for informing an observer of time remaining to a given event, time elapsed since a given function, and/ or distance traveled in said time interval.

The device of the present invention has numerous uses in fields that are unrelated to one another such as advising progressive time intervals and distance traveled in the sum oi said intervals and the time and distance to go to a given point. A specilic example of this use would be the spotting of a iiying object, a given distance and time from a point of landing, setting this information into the device and having the device automatically and continuously inform the observer of the decrease in time and decrease in distance that the said dying object is from its point of landing, rendezvous or observation. Conversely, a flying object may have its flight initiated and this information imparted to the device and which then automatically at given intervals informs the observer of the time elapse and the distance traveled since commencement of llight of the object.

Another use for the device of the present invention would be in the carrying forward of manufacturing processes and wherein different steps in the process, such as adding ingredients or raising or lowering temperature, are to be effected at definite time intervals and with the device indicating the completion of those time intervals. Other uses of the device are hereinafter set forth.

The principal obiect of the present invention is, therefore, the provision of a device that may be designated as a traveling memory or moving events display device that either subtracts intelligence from or adds intelligence to the initial point at which the memory or event was started.

Another object of this invention is the provision of a device that accomplishes the foregoing obiect but which can have the memory erased ir" for some reason it is desired not to continue the same and, conversely, the said memory be initiated at any point along a tracking or recording path.

A further object of the present invention is the provision of a device for accomplishing the foregoing objects and w ich device simultaneously completes a memory track or a recording record of a plurality of individual events.

Other objects and advantages of the present invention should be readily apparent by rererence to the following specification considered in conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modiiications may be made in the exact structural details there shown and described, within the scope of the appended claims, Vwithout departing from or exceeding the spirit ofthe invention.

Throughout the several views of the drawings similar reference characters are employed to denote the same or similar parts. Y Y

As noted above the device of the present inventionris adapted to act as a moving events display or as an indicator of present action and keep an observer continuously informed of the progress of the action.

As will later be more specifically pointed out the device of the present invention may be arranged and used to continuously inform an observer of the approach of an airplane to a landing field. At the same time the observance of other airplanes flying toward the ield, or point of observation, can have their flying progress individually and independently charted. This Vrecord can be commenced at any point within the range of the device and if two or more planes are approaching the landing iield, or point of observation, their independent progress can be charted and observed even though they are each` a dilierent distance from` the ield and thereby requiring different elapsed time intervals to thelanding point and their individual progress continuously observed and noted.

Specically and as shown in FIG. 1 use is made of a panel 15 which conveniently may be the front of a box or cabinet le, see FIG. 2. The cabinet front or panel i5 has mounted thereon a plurality of horizontal rows of lamps 17 with each lamp in each row vertically aligned to provide vertical columns and which lamps may take any convenient form with the lamps in a horizontal row .employed to indicate the progression of the moving event in the tracking or control sequence. Y

As shown in FIG. 2 the said Vlamps 17 may each be a removable part of a switch operating mechanism indicated in its entirety by the `reference numeral i3 and which switch operating mechanism includes a plunger body portion 19 from which projects, per se, a plunger 20. The plunger body portion 19 is mounted for sliding movement through anfaperture 2l in the cabinet front or panel 15 and preferably is associated'with a bracket 22 secured through a depending ange 23 to the inner face of the saidrcabinet front or panel 15. The bracket 22 is illustrated as U or channel shaped with a second flange 24 inwardly'spaced` from the rst flange 23 and downwardly projecting. An inwardlyprojecting horizontal arm 25 from the flange 24 has at its inner edge a depending ilange 26 to the outward face of which is secured atrack 27.

3 The bracket iiange 26 in turn supports a further bracket 28, inwardly of the bracket 25, with said bracket 28 also including a depending ilange 29 carrying on its inner face a track 30.

It should` be noted that the brackets and 28 may be formed as a unitary construction and with the said brackets, or bracket, extendingrentirely across the inner face of the cabinet fron-t or panel behind a horizontal row of lamps 17 and that there is a similar construction for each horizontal row of lamps 17 and with said brackets extending parallel to one another vertically of the cabinet n front or panel 15.

Y and 33, shown diagramatically in FIG. 6. Each of the shafts 32 and 33 is mounted for rotation in any suitable or desirable Ymanner such as through a bearing 34, see FIG.

2, secured to the cabinet base or bottom 35. Secured, K

respectively, to the said shafts 32 and 33 are pulleys or belt drums 36and 37 in transverse ,alignment and around which extendsy the endless belt 31, there being as many pulleys or belt drums on each shaft as there are horizontal rows of lamps. It should be noted that the pulleys or belt drums 37 may be freely rotatable on the shaft 33 while the pulleys or belts drums 36 are each secured to the shaft 32; for this purpose the said pulley or drum 36 is'illustrated in FIG. 6 at 38 as keyed to the shaft 32.

As illustrated in FIG. 1 the lamps 17 are equally spaced from one another transversely of the cabinet front or panel 15.` Secured to the belt 31 immediately behind and in alignment with each lamp 17 is a switch mechanism indicated in its entirety by the reference numeral 39 and a description of one such switch mechanism will sutice for all.

The switch mechanism 39 is a commercial product and Y may take any acceptable form or construction and is designated as a single pole, single throw switch including a supporting bracket 40 secured through an attaching member, rivet or the like,41 to the endless belt 31. Each switch bracket 4() includes a base 42 `from one side of which extends the attaching means 41 while against the opposite or outward face of the base is a switch slide 43. The switch Vslide 43 is adapted to be vertically shifted which movement, as seen in FIG. 3, is effected through a spring 44 extending between the said slide 43 and a switch actuator 45. The switch actuator 45 is adapted to be oscillated on a trunnion or pin 46 extending through the actuator and through supporting arms 47 of the switch sup- .i

porting bracket andk whichextend outwardly vfrom the switch bracket base 42. The switch actuator 45 is provided with a pair of Seats 48 and 49 adapted to be alternately engagedby and upon operation of the switch operating mechanism plunger 270.k Y Y.

The switch slide 43 has `secured'to its upper end ars'witch or contact plate 50 adapted to co-operate with `contacts 51 and 52 for bridging same and permitting a current flow therebetween. The contacts` l51 and 52 are secured in spaced relation to one another to a carrier 53 formed of insulating material and which carrierY 53 is connected to the underside of the bracket horizontal arm ,25 as clearly illustrated in FIGS. 2 and 3. e Y y As shown in FIG. 3'the contact 51 hasrconnected there-Y tacts 52 may be a segmented buss bar with each segment separated from the others and there are as many said separate or segmented buss bar contacts as there are lamps 17 wherefore a separated segment of bussbar or sliding contact A52 is provided for each lamp 17.Y

In practice the endless belt 31 is advanced ina given direction, toward the left as in FIG. 6, thereby advancing the switch mechanism successively from one segmented buss bar or sliding contact 52 to the next while maintaining continuous contact with the continuous buss bar 51. From this it follows that the lamps in a horizontal row are successively illuminated as the switch advances from right to left in FIG. 6. Y

Any suitable or desirable means may be employed for effecting the advancing movement of the belt 31 that shown in the drawings comprising a solenoid coil 57 associated with the shaft 30 for intermittently energizing a ratchet mechanism 58. The arrangement of these parts being such that the coil 57 and ratchet 58 advances the belt 31 from one lamp to the next at each impulse or activation thereof.V In order that the said solenoid and ratchet be energized the said solenoid 57 has one side thereof connected to ground while its other side is connected by a wire 59, a make and break switch 60, anda wire 61 to a source of electric'current, preferably a direct current source or voltage. The make and break switch 60 is operated by a plunger 62 associated with a solenoid 63 in turn having one end of its coil connected to ground while the other end thereof is connected through a wire 64 and a make break switch 65 with the wire 61 and the DC. voltage. The make-break switch 65 is intermittently closed by a cam 66 secured to and continuously rotated by the shaft 67 of an electric motor 63 connected preferably with an alternating current source or voltage by the wires 69. n

The continuous buss bar 51 has its electric conductor or wire 54 connected with the direct voltage current wire 61 and through theV switch mechanisms 39 with one side of i the lamps 17 whilel the other side of said lamps 17 are connected with a wire '79 that is connected to ground and whereby, when a switch mechanism 39 is completed, the circuit to the said lamps isindividually maintained.

' From the foregoing it will now be understood that ,there is provided a switch mechanism behind each lamp 17 and it is to be noted that each lamp has associated :therewith a switch `operating plunger 2@ wherefore said switches may be actuated through any light plunger in a horizontal line. It should further be noted that the switches are ofthe variety known as push-push-ON-OFF switches. In other words the operation of a lamp plunger would, for example, operate the switch'to illuminate the light and return to a neutral position whereupon asecond push operation on the lamp plunger wouldy extinguish the lamp. Since the arrangement is such that each switch is subsequently aligned with each lamp plunger the said switch can be operated to illuminate or extinguish the lamp at any point in a horizontal row, all as will be presently further defined.

As will be noted from FIG. 6 the entire length of the lbelt 31 is provided with switches each equally spaced Y from adjacent switches but the switches, at any given time,

immediately Vbehind a push lamp are the only ones that can be closed for illuminating or extinguishinga lamp and conveniently this is arranged to take place for the outward reach of the belt. In the operation of the device,

again as will bc presently made clear, the switches are to be opened as they pass the last light. Any suitable or desirable means may be employed for this purpose, that shown'diagrammatically in FIG. 6 comprising a member including a stem 71 and an arm '72 with said arm positioned to operate on the switch actuator 45 and which operation would be such that the actuator-45 is oscillated or actuated to the opposite position from that shown in FIG. 3 and which would be the switch-off-position, if the switch actuator is in the position shown in FIG. 9 it would not be actuated by `the means 71-72.

In prac-tice the motor 68 is such Vthat a complete or single revolution of its shaft` 67 takes place in a given elapsed period yof time, such as two and one-half minutes. In this circumstance the make and break switch ,65e/Ould be closed, momentarily, every two and one-half minutes onstaat for energizing the solenoid 63, closing the switch 6i), and energizing the solenoid coil S7 and ratchet mechanism 53. This then would advance the endless belt 3l a given amount every two and one-hair minutes, or advance the switch from one lamp .to the next every two and one-halt minutes. In this connection it should be noted that the relation of the Iswitch plate Sti to the individual segmented buss bar contacts 52 is such that the illumination of any one of the lamps 17 would be followed almost immediately by the extinguishrnent of the previously illuminated lamp so that ,the illumination of more than one lamp in a horizont-al row is held to an -absolute minimum once a lamp in said row has been illuminated. Alternately the relation may be such that the successive lamps are illuminated only after the extinguishment of the preceding lamp but this interval is again held to an absolute minimum so that a single, illuminated lamp, is substantially constantly in operation.

in this connection it should also be noted that the movement of the belt 3l is such ,that the switches are advanced from position to position at such a rate that a switch is always in position to be operated, that is, -it is almost impossible to actuate a switch control device, switch plunger l-Ztl, without a switch being present to be operated thereby.

The cabinet front or panel l is provided at its upper end with a series of windows 73 and which windows would carry indicia and with a window directly above each vertical column of lamps. The said windows 73', in accordance with the above example of motor o8 speed, would each carry a time indication in minutes with such indication two and one-'half minutes apart and wheretore said windows are respectively marked, from left to right, 21/2, 5, 71/2 etc. to and including thirty minutes as presently set up and disclosed in the drawings as an example.

The horizontal rows of lamps are also provided with indicia, which for an example of use to be presently made clear, the marldngs are from 5 to 25 both inclusive, in increments of l.

it is to be understood that the horizontal row markings and the vertical column markings would be changed depending upon the use to which the device is to be put.

The device of the present invention is illustrated in the drawings as having been set up t-o keep a moving record of a moving object, such as an airplane, wherefore an observer would know how far from the observation point the airplane is and approximately how much time remains for the airplaneto reach said yobservation point at any Vgiven moment within the control or critical area that the observer is concerned with. For this reason the horizontal row inditing numerals, 5 through 25, may represent thousands of feet of altitude of an airplane.

Specifically, it is to be assumed that an airplane is sighted within thirty minutes rom the airport at which the observer is located and that the airplane is 25,090 feet in altitude. The observer in this instance would perate the switch plunger l-Zl in the vertical column under the numeral and in the horizontal row preceded by the numeral 25, said lamp plunger being specilically identitied in FIG. l by the reference numeral lcz. The closing `ot the light plunger 17-20 operates the switch associated therewith to the position illustrated in FlG. 2 for thereby connecting or completing the circuit for illunfnating the said lamp 17a. A

it is to be understood that the control mechanism behind the horizontal row 25 is intermittently operated wherefore within 21/2 minutes following closing of the switch plunger llcz, FG. l, the lamp immediately preceding it will be illuminated :and said lamp 17a extinguished and that each 21/2 minutes thereafter the said illuminated lamp extinguished and the preceding lamp illuminated. The observer need, therefore, but glance at the cabinet front or panel l5 to be advised at anytime of the position of the airplane, in so far as time to ultimate landing is concerned.

l said lamps are arranged in FG. 1.

f5 Assuming now that a second airplane is observed at the 20,000 feet altitude and that it is 25 minutes from the airport. In this instance the operator would operate the switch plunger 117-26 in the vertical column under the numeral 25 and in the horizontal row preceded by the numeral 20 whereupon said lamp would be illuminated until the airplane has reached a landing at the point of observation. This last mentioned light plunger is specifically identitied by the reference numeral Ilb.

Similarly any other airplane within the radius or area under the control of the observer may be set up in the device of the present invention and its movable progress at all times indicated.

If it now be assumed that between the times of obsen vation and the anticipated time of landing it is desired that the plane move away from the originally intended landing point so that the observer need not concern himself therewith any further it is only necessary for the observer to actuate the light plunger 17%@ then illuminated whereupon the switch controlled thereby will be opened extinguishing the lamp and which will not furtherV be illuminated unless deliberately operated. Y

Specifically, and assuming that the lamp lb represents the airplane originally twenty-ve minutes from the point of observation and that the said airplane is diverted trom its course when the same is approximately ten minutes from the said point of observation. The lamp plunger 17-Zil, specifically identiiied by the reference numeral 17C, in the vertical column of lamps headed by the numeral l0 and in the horizontal row of lamps preceded by the numeral 20, is then operated, which as noted above, opens the switch to the lamp thereby extinguishing the said lamp lc and which lamp, along with all that remain in said row, will remain extinguished unless a light plunger 17-20 between 17C and the left hand end of the row Zt) is pushed for again illuminating a lamp.

The foregoing description speaks of illuminating and extinguishing the lamps, however, the specific function is the opening and closing of the moving switches which successively illuminate the lamps carried by the cabinet front or panel l5. It is believed obvious, however, that the moving belts may support a plurality of lamps instead of switches and with the switches, per se, carried by the cabinet front or panel and when one switch is closed each of the succeeding switches in the row will be correspondingly closed while each switch similar to each lamp will be open if the switch or lamp immediately ahead of it is open.

In the event the airplane continues to move` after its observation and itsV position entered on the cabinet front or panel l5, until it reaches the airport, the switch initially operated will be automatically opened by the switch opener ll-72?.. Y

It is to be noted and understood that instead of a solenoid operated ratchet, such as 5d above, for intermittently and angularly moving the shaft 32, belt 3l and switch 39, a standard and well known step operated motor may be employed. This type of mechanism is well known and may be exemplified byV a Ledex rotary solenoid motor as made and distributed by Ledex, Inc., Dayton, Ohio.

The modiied structure disclosed in FlGS. 4 and 5 contemplates a separate plunger and lamp mechanism. As shown, particularly in FlG. 5, the lamp 73 is mounted in a lamp socket '7d connected by a wire Se with the segmented buss bar or separate-slide contact 52. VAs will be seen from FIG; 4 the said lamps ll'7 are arranged in a horizontal row in substantially the same manner as the The operating mechanism or plunger however consists of a cap member '75 separate and apart from the lamp 17 with said cap having projecting `there'trom'the rod or plunger 76 encircled by aY spring T whichnormally re-V tains the said plunger 76 and its cap 75 in the neutral or inoperative position; the spring 77 is shown 'asV abutting on one end with the base of a counter-bore in .the cap 75 and abutting on its other end with the depending flange 24 of bracket 22.

The plunger 76 co-operates with a switch actuator 45 of the switch mechanism substantially identical with the push-push switch above described.

The circuit of FIG. 6, above described, is actually the circuit involved in the mechanism of FIGS. 4 and 5 since the said circuit diagrammatically includes a plunger 76 separate from the lamp but it is obvious from FIG. 6 that if the lamps there illustrated, and as illustrated in the upper part of FIG. 10, were movable they would Contact and move the plunger and thereby close the switch. In connectionV with the electrical diagram in FIG. 6 it should be noted that the switch member slide 43, as structurally illustrated inFIGS. 2, 3 and 5 is illustrated in FIG. 6 as a pivoted contact member which is electrically connected with theV said segmented buss bar sections or separate slide contactors 52 while the elongated or con-V tinuous buss bar 51 is shown as having an electrical contact extending therefrom. Further, as shown in FIG. 6, the third switch from the right hand end is shown as being closed this would correspond with either switch 17a or 17h of FIG. 1 or, corresponding with switch 75a or'75b in FIG. 4.

The foregoing modifications deal with, as the title of this application indicates, with events that are to take place within a time band and toward a conclusion of the event.

In the modification illustrated in FIGS. 7 to 10 it is contemplated that certain moving events may take place in a succeeding time interval as distinguished from the event being accomplished or effected in a time cycle where# in the time diminishes. Accordingly the panel or cabinet front 15 in FIG. 7 discloses a plurality of pairs of horizontal rows of lamps respectively identified by the refierence numerals 78 and 79 which forrconvenience and space savingrmay be similar to the construction illustrated in FIGS. 1, 2 and 3.

o respectively, the upper arm carrying bridging contact 103 and the lower slide arm carrying bridging contact 104.

The bridging contact 103 is adapted to bridge or connect a continuous buss bar contact 105 and a segmented bar or individual sliding contact 106l while the bridging Contact 104 is adapted to connect a continuous buss bar contact 107 and a segmented bar or individual sliding contact 103 with saidcontacts 107 and 108 being carried by and through an insulated carrier on the bracket arm 92 while thecontacts 105 and 106 are similarly carried by and through an insulated carrier on the bracket arm 91.

The segmented or individual contacts 106 are, respectively, each connected with a lamp 78 through a wire or conductor 105i while the segmented or individual contacts S are, respectively, connected with a lamp 79 through a wire or conductor 110.

In practice the endless belt 97 carrying the switches 99 is mounted on drums 111 and 112, see FIG. 10, while the endless belt 98, carrying the switches 100, is similarly mounted about drums 113 and 114. The drums or pulleys 111 and 113, as diagrammatically illustrated in FIG.

As illustrated in FIG. 8 the lamps 73 are each mounted Y in a socket 81 while the lampsr79 are each mounted in a socket S2.. The said lamps 7d and` 79 and their respective sockets each form theoperating mechanism ofA a pushpush-ON-OFF switch.

As first noted, the lamps 7S and 79 are similar to the lamp switch actuating mechanism constructionof FIGS. 1, 2 and 3 and wherefore the lamp 73 and its socket 81 are a part of a plunger housing mechanism 83 from which extends the plunger, per se,f34l held in normal or inoperative position by a spring S5. `Similarly, the lamp 79 and its socket 82 are carried by and form a part of'plunger housing 86 from whichl extends the plunger S7, heldin its normal` inoperative position by a spring 88.

The lamp and switch operating Ymechanism extend through suitable apertures in the cabinet front or panel and are further associated with and carried by a bracket S9 that extends transversely of the said cabinet fronty or panel 15V in-the same manner that bracket Z2, above, extends with respect to cabinet front or panel 15.

A second boxlike bracket 90, secured to the bracket 89 through arms 91 and 92, has, in turn, securedto the outer face thereof a track 93 and has secured to vits'inner face a track 94. The tracks 93 and 94 are each provided with an upper trackway $5 in alignment with one Yanother and said tracks are further each provided with a lowerv trackway 96, likewiseV in alignment with oneanother, and with said trackways, respectively, receiving and guiding endless belts 97 and 98. The said belts 97 and 98 each have secured thereto a plurality of Switch mechanisms,

such as disclosed inFIG. 8,.'andgwhereinV saidV individual switch mechanism are,.respectively, indicatedin its kentirety by the reference numerals 99 and 100 and which switch vmechanisms, are substantially identicalV with the switch mechanism 39 above described, andfeach switchV Y mechanism including a switch slide 101 and `1.02, re-

spectively, having Yat one end thereof, as seen inFIG. 8,

l0, are mounted on the shaft 32 while the drums or pulleys 112 and 114 are mounted on or associated with shaft 33. The said belts 97 and 98 are actuated in opposite directions namely the belt 97 is driven by the drum or pulley 111 which is rotated in a clockwise direction while the belt t; is driven or rotated by the pulley or drum 114 which is driven in a counter-clockwise direction. this reason the pulley or drum 111 is keyed, as at 115, to the said shaft 32 while the pulley or drum 112 is freely mounted on the shaft 33 through a bushing 116, and, conversely, the drum or pulley 114 is keyed as at 117 to the shaft 33 while theV pulley or drum 113 is freely mounted on shaft 32 through a bushing or sleeve 118.

From this itrfollows that even though the shaft`32 is rotated in a clockwise direction carrying withV it the drum or pulley 111 the drum or pulley 113 is not moved thereby and conversely the rotation of the shaft 33 in a counter-clockwise direction carries with it only the drum or pulley 112.V Consequently, also, the said drums or pulleys 111 and 112 along with the belt 97 may be operated or actuated in'one direction while the pulley or drums 113 and 114 along Lwith the belt 98 are operated in an opposite direction.

The shaft 32, as illustrated in FIG. 10, is rotated or actuated in the same manner as above set forth, namely, through an intermittently energized solenoid coil 57 associated with,y for intermittently operating, a ratchet mechanismV 58. lTo rotate the shaft 33 a similar but oppositely operating mechanism isy employed, namely, a solenoid coil 119 associated with for operating a ratchet mechanism 120. The direction of rotation of the ratchet mechanism 5S is, as noted above, in a clockwise direction as indicated by the arrow 121 thereon while the ratchet mechanism 120 is actuated in a counter-clockwise direction as indicated by the arrow 122 thereon.

In order t-o energize the solenoid coil 119 it has one end thereof connected by a' wire1123 to the wire 59 ahead of the make break switch 60.y The other end of the solenoid coil 119, similar to the solenoid coil 57is connected to ground.

f The continuous contact or buss bar 107 is connectedV with the wire 61 Vthrough a wire 124 while the segmented or sliding contacts 108 each has connected therewith one Y side of the filament in a lamp 79 while the other side of the lamps are connected to the ground wire 70.

From thepforegoing it will be noted that the endless belts 97 and 9S are actuated in Areverse directions, that is, the forward reaches of the belts 97 travel from right to left as seen'in FIG. 10 while the forward reaches of the belts 93 travel from left to right. Correlating this with the cabinet front or panel 15'.' Vthe lower row of lamps in each of the rows preceded by the numerals 5 through For All'

25 has the lamps successively illuminated when moving from the left to the right while the upper row of each of said double rows of lamps has its individual lamps successively illuminated from right to left. In other words the lower row of lamps may commence at theV vertical row marking 21/2 and advance to 30 while the upper row may commence at or even before the vertical row under 39 and proceed downwardly to 21/2.

lt will also be noted that the lamp plungers 7S-84 and 79-87 may be operated at any point between the extremes and the lamps either preceding the same or succeeding the same will then be illuminated. By the same token should it be desired to remove the intelligence from the device the illuminated lamp may be extinguished and thereby prevent the lamps to be next illuminated from operating.

A concrete example, in line with the above, may be illustrated by assuming an airplane is sighted 30 minutes from an airport or point of control and at, for example, 24,0% feet the operator would depress the lamp or switch control S-Sd in the vertical column under 30 in the upper set of lamps in the horizontal row 24 and thereby illuminate the lamp indicated by the reference numeral 'i341 and proceed to forget about it since all he would have to do would be glance at the cabinet front or panel to know where the said airplane would be. Assuming now that an airplane is departing from the airport at about the time of observance of the plane thirty minutes from the airport the operator would then depress or actuate the lamp or switch control 79-87 in the column under the 2l/2 and, again, if desired, in the lower set in the row 24 and illuminate the lamp at this point, such as lamps 79a and again proceed to forget about it since a glance at the cabinet front or panel would again inform him of the progress of the airplane away from the airport or point oi' observation. It will be understood that the adjacent lamps in the direction of movement of the airplanes would be successively illuminated at denite intervals such as 21/2 minutes, or units of time, in the progress of the said airplanes.

Again, and in line with the above example, and assuming that the airplanes deviate from the intended pattern so that the observer need not further concern himself with the airplanes it is only necessary at this point t operate the lamp or switch control of the then illuminated lamp whereupon further tracking is prevented or the memory erased from the device.

In the event the departing plane continues on schedule, the switch mechanisms 160, similar to the switch mechanisms 99, corresponding to the above indicated switch mechanism 39, are automatically opened at the remote end of their travel by a switch opener, in all respects similar to that above described, and including an arm E25 from which extends a finger 126. v

To further assist the operator in his control and observation of the movement of the airplanes the lamps in each row or each pairV of parallel rows could be of a different color, namely, the lamps 7 could be red to indicate an airplane coming in, or time to go, to the airport or point of observation, while the lampsv79 could be green to indicate the time elapsed since the commencement of the airplane tlight or the time the airplane has been in fright.

The foregoing has dealt with the use of the device in connection with the tracking of and information pertaining to airplanes to and from an'airport or point of observation. It is believed obvious that the device of the present invention could be readily adapted to the control and observation of moving trains to and from a railroad station, classification yards, or division points. The device of the present invention may be employed forcarrying forward manufacturing processes, such as the time or point at which temperatures should be increased or decreased,

. i@ the time or point in the process when additional ingredients are to be introduced or byproducts taken o, or in the control of the process when batches of dilerent quantities are being handled. The device of the present invention can also be employed as a counter -such as counting decades or multiple units.

In each of the above examples the device is employed as a moving events display or a traveling memory relieving the operator or control individual of the necessity of remembering when the several events in a chain are to be effected since a glance at the panel will readily inform him of the time that the said action on his part should be effected. It will further be noted that the device, at the conclusion of the event, or after Vthe function has been completed, is cleared of any memory thereof, that is, the closed switch or switches are automatically opened, and remains clear until subsequent new data is positively fed or initiated into the device.

It is believed obvious that the indicia at the upper end of the panel and above the vertical rows of lamps would be readily changed to accommodate the particular use to which the device is being put and likewise the indiciarto the left and/ or right hand side of the horizontal rows of lamps likewise changed or made appropriate to the particular problem being handled.

From the foregoing it is believed now obvious there has been provided a device for accomplishing the objects initially set forth.
